Changing a defined alternate path priority

To change the alternate path's priority, use the Priority Up and Priority Down commands displayed
in the Path Setting window (

Figure 52 (page 98)

).

Priority Up: Raises the priority of the path selected in the Alternate Path list.

Priority Down: Lowers the priority of the path selected in the Alternate Path list.

As long as the external array uses Symmetrical Active/Active controllers (for example, XP), change
an alternate path to the currently used path by simply raising the priority of the alternate path or
lowering the priority of the currently used path.
